   Lambda Science personnel enjoy the challenge of the most difficult technical problems that arise in advanced active and passive sensor systems.  The company’s specialty is advanced electromagnetic sensors with applications in radar.  Expertise includes surveillance, tactical, instrumentation, HF over-the-horizon (OTH) and synthetic aperture radar (SAR).  The company also maintains expertise in acoustic sensors (e.g., underwater towed array systems), and electro-optic/infrared (EO/IR) sensors (e.g., infrared search and track (IRST), multispectral systems, etc.).  The staff maintains theoretical and practical capabilities that include rigorous analytical performance prediction involving sensor and environment modeling, to custom experiment design and hands-on hardware performance evaluation. The staff has significant experience in end-to-end system design and development, subsystem design and development, and advanced signal processing.  End-to-end system design experience includes almost all types of military radar.  Subsystem design includes conventional antennas and phased arrays, direct digital synthesis exciters and high power transmitters, low noise high dynamic range receivers, and transmit/receive (T/R) modules for phased array system architectures.  Advanced signal processing techniques include low IF sampling digital I&Q filtering and channel equalization, large time-bandwidth product waveform design and associated processing, detection, tracking and fusion algorithm development, and the design and application of spectral estimation and time-frequency analysis techniques for the characterization of non-stationary processes.  In addition, the company has an excellent understanding of propagation and scattering phenomenology, and expertise in many applications that must mitigate and/or exploit this phenomenology.
